oh-my-hermes is an operating layer for Hermes Agent that organizes requests into workflows for planning, research, creation, coding handoffs, operations, and project memory. Hermes users run these workflows through the desktop app, CLI, or messenger app, while the catalogue add-ons extend its native capabilities.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.02093 |
| Opus 5.5 | $0.00030 | $0.00837 |
| Sonnet 5.5 | $0.00015 | $0.00419 |
| Haiku 4.5 | $0.00007 | $0.00209 |
Grade A, and why
omh-rust scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rust
This is an OMH rust workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
Why This Exists
rust closes OMH's zero-coverage Rust domain and makes the escalation from ordinary Rust work to undefined-behavior discipline a deterministic routing rule rather than something a model is trusted to notice.
Do Not Use When
- The request is a server, API, or schema design that happens to mention a Rust stack; use
omh-backendfor the contract and name Rust as the stack. - The request is debugging a stripped or source-less native binary; use
omh-native-debugging. - The request is a general code review of finished Rust; use
omh-code-review. - The request is a Rust vocabulary or concept question with no change to prepare; answer it directly.
Examples
Good example:
- Prompt: Rewrite this parser in Rust and fix the borrow checker errors.
- Expected behavior: Prepare rust_change_contract/v1 with the escalation verdict, ownership_shape/v1 for the parser's borrows, error_and_api_contract/v1, and rust_gate_list/v1.
- Why: The request is a Rust change whose difficulty is ownership shape, which is exactly what the contract has to settle before code.
Bad example:
- Prompt: It compiles and the unsafe block looks fine, so call the FFI wrapper safe.
- Expected behavior: Escalate on the
unsafe/FFI trigger, mark Miri and sanitizer evidence as not_observed, and name them as blocking items. - Why: Compilation proves nothing about the invariant an
unsafeblock asserts, and the escalation is not optional.
Completion Checklist
- The escalation verdict is stated with the trigger that decided it.
- The ownership shape names owners, borrows across boundaries, and every deliberate clone.
- The error type, its conversion boundary, and every surviving
unwrap/expect/panic!are named. - The gate list names the exact commands the executor must run and pass.
- An escalated change carries the Miri, sanitizer, and concurrency-testing requirements as blocking items.
- Compiler, clippy, test, Miri, sanitizer, and loom results stay observed-only.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

omh-rust is a skill published in the GitHub repository rlaope/oh-my-hermes (4,206 stars, last pushed today), licensed MIT. It adds 74 tokens to every session and 2,093 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
